L 1 To allwho'm it may concern:

Beit known that we, JAMES F.\MANNING and A. DnNsLINenn, citizens of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a .certain new and useful Improvement in Shoe-Finishing Machines, of which the following is a specification.

Our invention relates to a new and useful improvement in shoe finishing machines, and has for its objectto provide an exceedingly simple and eii'ective device of this character whereby shoes may be ground, polished and the like.

Another object of the invention is to provide a machine of the character described which is adapted to carry a number of grinding and buffing wheels, any one of which may be readily and easily brought into operative position.

A further object of the invention is to provide housings'for the grinding wheels and a means connected with said housings for carrying off the particles of leather which are ground away.

With these ends in view, this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims. In order that those skilled in the art to which this invention appertains ,may under-' and bufling wheels, and Fig. 5, a sectional side elevation of the levers for operating the belt shifter and cam roller. p

In carrying out our invention as here embodied, A represents the frame of the with which registers the cam roller E operated by the bell cranklever F, one end Letters Patent.

' I of which is connected to the cam roller b the link G, the opposite end of said fbefi crank lever being connected by the rod H to the extension" I, mounted on the shaft J which carries the pedal K. On the shaft B is also mounted the external drum L carrying the polishing or bufiing wheels M and the grinding wheels N, each of said grinding wheels having a housing 0 from which leads a port P. When one of the grinding wheels isin o erative position the port P will be inalinement with the port Q; formed in the internal drum R, which is loosely L. In the drum R is placed a weight S which will always hold or bring the port to one position.

The grinding wheels and bufling wheels may be mounted in pairs, that is, one set set along the other edge, and each pair of these wheels will bemounted upon a shaft T carrying a pulley U on one end. On the opposite end of each of these shafts is placed an edge setter A The pulley whlch is mounted uponthe shaft of the wheels which are in operative position will be in alinement with the pulley V mounted on a shaft W journaled to the frame. Upon these pulleys runs a belt X which also runs over the which the power is applied in any desirable manner. This belt runs through a belt shifter A which is connected bye suitable means to the link Gso that the same will be operated when the camroller is moved in and out of engagement with the notches'D belt from the pulley V to one of the pulleys U or vice versa. On the shaft Z is also mounted the pulley B over which runs a .belt C saidbelt also running over the pulley D mounted upon the shaft B, it being understood that this belt C isvery loose so that ordinarily it will not revolve the pulley D, but when the pedal K is pressed downward the extension I will be operated which'will pull upon the rod E drawing the tightening ulley F against the-belt C which will t1g ten said belt sufiiciently to cause the pulley D to revolve. This tightening pulley F is journaled in the lower end of the swinging bracket G which is pivoted to the clamp I-I fastened at some suitable point upon the frame A.

along one edge of the drum L and anotheron the cam wheel C. This will move the leading from t e housing about that wheel I mounted upon the shaft B within the drum drive pulley Y mounted on the shaft Z to v I denotes a shaft, the ends of which are journaled in the frame and on this shaft is mounted the locking arm J having a notch K in proximity to its outer end and provided with a lip L. This arm is operated by the lever M pivoted to the lug N mounted upon the frame, and said lever is connected by the rod 0 to the extension I. Between the arm J and the lever M which operates is placed a spring P for relieving the shock prevalent 1n the movements of engaging and disengaging the arm J with or from the shafts T of the wheels. On the shaft Z is mounted a fan Q, having an exhaust port R, and this'fan is connected with the inner drum R by the conveying tube S so that the chips within'the drum R will be withdrawn and exhausted through the port R. If found desirable the pulley Y and the fan Q, may each be provided with a friction clutch T for throwing them in and out of gear so as to stop the working of the parts of the device to which they are connected.

In practice the wheels which are mounted on the shaft having its pulley U in alinement with the pulley V are the ones which are in operative position and when in this position the notch K in the arm J will be in engagement with the shaft T of the wheels which are in operative position, and the cam roller E will be in engagement with one of the notches D formed in the periphery of the locking cam-wheel C. When for any reason it is desired to bring any of the other dressing wheels in o erative position, the pedal K is pressed ownward which will do likewise wlth the extension I through the medium of the shaft J. This will move the arm J out of engagement with the shaft T, at the same time disengaging the cam roller E from' one of the notches D and will also cause the tightening pulley F to draw the belt C out, at the same time the belt X will be shifted from the pulley Uto the pulley V. At this time motion will be given to the pulley D through the belt 0, from the shaft Z which will cause the outer drum L to revolve until the next succeeding pair of wheels M or N are brought into operative position. As soon as the locking cam wheel 0 has revolved suificiently to remove the notch which was engaged by the cam roller away from said roller, the pressure may be relieved from the pedal and the cam roller will rest upon the periphery of the locking cam wheel until the next succeedin notch D has come into position, at which time the cam roller E will drop into said notch. This will allow the pedal K to move upward so that the pressure upon the belt 0 will be relieved and the notch in the locking arm J will engage the shaft T of the dressing wheels which have come into operative position, at the same time the belt X will be shifted to the pulley U, when the dressing wheels will be revolved.

While using the grinding wheels the chips or dust will e caught by the housing, and because \of the action of the fan Q they will be drawn into the internal drum R, then through the pipe S and expelled from the exhaust R.

Of course we do not Wish to be limited to the exact details of construction here shown, as these may be varied within the limits of the appended claims without departing from the spirit of our invention.

Having thus fully described our invention, what we claim as new and useful, is
